I’ve always found saliva fascinating.
We think of it as just… saliva. But when I’m looking in someone’s mouth, it gives me another little piece of information.
In this case, I’m checking the pH.
I like to see it close to neutral because our teeth are constantly going through this little exchange of minerals. When the mouth becomes too acidic, the balance shifts toward minerals leaving the tooth rather than going back in. That’s when I start thinking about cavity risk and the environment around the gums too.
And then I ask why.
What are you eating? Are you getting enough minerals? How is your digestion? Are you breathing through your mouth and drying everything out?
A saliva pH test isn’t going to diagnose what’s happening elsewhere in the body. But it can give me a clue, and after all these years in dentistry, I’ve learned not to ignore the clues.
The mouth has a funny way of telling us when something deserves a closer look.
That’s the part of biological dentistry I love most. Teeth are important, of course. But there is usually a much bigger person attached to them.
